The history of the ancient geared mechanism found in a Roman shipwreck near the Antikythera island is reviewed. A particular attention is devoted to the notices in the contemporary literature (Cicero, Vitruvius), which yield an evidence of a long tradition in development of similar analog computers in ancient Greece for calculation of the positions of celestial bodies. The results of The Antikythera Mechanism Research Project based on X-ray computer tomography are summarized and the functions of the proposed reconstruction of the device are explained.
